doc: fix documentation about uio_hv_generic

The vmbus sysfs file names changed in
 commit f6b2db084b65 ("vmbus: make sysfs names consistent with PCI")
and the uio documenatation does not match the current names.

 Since the driver does not declare any device GUID's, it will not get
 loaded automatically and will not automatically bind to any devices, you
 must load it and allocate id to the driver yourself. For example, to use
-the network device GUID::
+the network device class GUID::
 
      modprobe uio_hv_generic
      echo "f8615163-df3e-46c5-913f-f2d2f965ed0e" > /sys/bus/vmbus/drivers/uio_hv_generic/new_id
 
 If there already is a hardware specific kernel driver for the device,
 the generic driver still won't bind to it, in this case if you want to

 You can verify that the device has been bound to the driver by looking
 for it in sysfs, for example like the following::
 
-        ls -l /sys/bus/vmbus/devices/vmbus-ed963694-e847-4b2a-85af-bc9cfc11d6f3/driver
+        ls -l /sys/bus/vmbus/devices/ed963694-e847-4b2a-85af-bc9cfc11d6f3/driver
 
 Which if successful should print::
 
-      .../vmbus-ed963694-e847-4b2a-85af-bc9cfc11d6f3/driver -> ../../../bus/vmbus/drivers/uio_hv_generic
+      .../ed963694-e847-4b2a-85af-bc9cfc11d6f3/driver -> ../../../bus/vmbus/drivers/uio_hv_generic
